Application December 16, 1944, Serial No. 568,471

35 Claims. (Cl. 12-1) This invention pertains to the manufacture offootwear and relates more particularly to an improved method of andapparatus for use in lasting shoes, the present invention being afurther development of the invention set forth in the United Statespatent to Kamborian No. 2,251,284 dated August 5, 1941.

That patent discloses the employment of means, for instance a pair ofhelically ribbed rolls. for gripping the lasting margin of the upper andexerting such stress as to draw the upper snugly about the last, while,at the same time, tending to move the lasting margin in a directionsubstantially parallel to the edge of the sole, in other words settingup a relative movement of the shoe and the rolls; in combination withwiping means, e. g. a rapidly vibrating reciprocating wiper, which urgesthe stressed lasting margin inwardly across the edge of the sole intocontact with the bottom surface thereof to which it is secured bysuitable means e. g. by adhesive applied prior or subsequent to theupper drawing operation or by metallic fasteners.

The present invention embodies means whereby the underlying principlesof the above patent are attained. One object of this invention is theprovision of means whereby the shoe being lasted is held with the bottomof the sole in a horizontal plane while the gripping rolls rotate uponaxes at an angle of the order of ten to fifteen degrees to the vertical.Another object of this invention is to provide means which will act uponthe lastingimargin before it enters the bite of the gripping rolls andbring it into a plane substantially perpendicular to that of the shoebottom. A further object of the invention is to provide an elementpositioned between the gripping means and the wiping means against whichelement the sole of the shoe being lasted is pressed by the operator,

over which element the lasting margin is foldedand by which elementadhesive is introduced between the lasting margin and the sole so thatthe lasting margin will adhere to the sole when wiped into contacttherewith, said adhesive being hot when introduced and having theproperty of setting quickly. A still further object of the invention isto provide as wiping means, two independently reciprocated blades soactuated and mounted that they move seriatim over the lasting margin andthat one or the other at least of said blades is in contact with thelasting margin until the adhesive has set sufilciently to oppose anytendency thereof to separate from the sole, one or both of said bladesbeing so mounted as to exert downwardly applied pressure upon thelasting margin. Other and further objects will appear from aconsideration of the following detailed description of one embodiment ofthe invention and of the accompanying drawings wherein,

Fig. 5 is a fragmentary side elevation, withparts in vertical section,illustrating one form of mechanism by which the lasting elements aresupported and actuated; and

Fig. 6 is a plan and Fig. 7 a vertical section respectively of thewiping unit.

Figs. 1 to 4 inclusive of the drawings illustrate the lasting of a shoeof the type known in the trade as a California," force-lasted, orsliplasted shoe. Such a shoe comprises an upper [0, a wrapper ii securedto or constituting an extension of the upper to provide a lastingmargin, a sock lining l2, the upper. wrapper and sock lining beingJointed as by a line of stitches l3, and a platform I l secured byadhesive or other suitable means to the sock lining. As shown at theright hand side of Fig. 1, the wrapper II is initially in a positionextending substantially parallel to the upper ill. The assembled upper,wrapper and sock lining are pulled over a last l5 prior to the assemblyof the platform therewith. Since the wrapper lasting operation is to beperformed with the shoe upside down, the wrapper may, for convenience,be described as initially depending, and corresponding language will beemployed in the description of the wrapper lasting operation.

The various elements by which the wrapper lasting operation is to beperformed are, in chronological order, a plow 20 by which the dependingwrapper H is raised or up-lasted, a pair of rolls 30 by which the upperI0 is stressed snugly enemas about the last I6 and the platform I4, anozzlelike device 40 by which the platform I4 is held down and throughwhich adhesive is supplied, and impact-wiping means 60 by which thelasting margin is wiped in and hammered down upon and secured to theplatform I4.

The plow 20 is reciprocated, as indicated by the double headed arrow 2I(Figs. 2 and 3) to engage and raise successive portions of the wrapperinto the plane of the bite of the rolls 30. The rolls 30 arecontinuously driven in opposite directions as designated by the arrows3|, 32 in Fig. 1. Each roll is preferably provided with helicallyextended ribs 33 and the inner roll, 1. e.- the one over the platform isprovided with a boss 34 against which the platform is held by theoperator. (See Fig. 2.)

The device 40 will be designated a hold-down applicator because of theseveral functions thereof, as set forth above. The applicator 40terminates in a toe 4 I, the base of which is, as shown in Fig. 4,substantially flat. During the lasting operation the shoe is held inposition by pressing the platform against the boss 34 of the roll 30 andthe base of the toe 4|. The shoe is preferably positioned with the edgeof the toe substantially at the edge of the platform and the uppersurface of the toe is inclined upwardly from the edge so that as thelasting operation proceeds the margin is bent over and in contacttherewith, whereby the wrapper is turned smoothly over the edge of theplatform and adhesive may be applied thereto as will be hereafterdescribed. When the platform I4 is made of fibre, rubber or similarmaterial, the operator, by pressing the shoe upwardly, causes the holddown applicator to compress the edge of the platform so that the wrapperwill be bent smoothly over the edge as indicated in Fig. 4. Theapplicator 40 is provided with a central adhesive transmitting conduit42 which terminates in an outlet passage 43 at the base of the toe H. 'Aroller 44, in an outlet passage 45 in the upper surface, transfersadhesive from the conduit 42 to the inner face of the lasting margin asthe latter moves thereover.

The final step in the lasting operation is performed by the wiping means50, here shownas two blades SI and 52 which are independentlyreciprocated transversely over the lasting margin as indicated by thedouble headed arrows 53 and 54 on Fig. 1. The wiping means 50 arepreferably so positioned that they act upon the lasting margin at anangle to the longitudinal axis of the shoe of the order of seventy-fiveto eighty degrees.

Various means for supporting and actuating the lasting elements may beprovided. Fig. illustrates one such means which follows in general theconstruction disclosed in the above mentioned United States patent. Amachine frame 60 suitably supported upon a bench or table (not shown) isprovided with a head 6| which extends forwardly of the front wall 62 ofthe frame. Mounted in bearings in said head is a horizontal shaft 63continuously rotated by any suitable means (not shown) within a casingor chamber 64. The portion of the shaft within the chamber is providedwith right and left hand worm threads 66 and 66 separated by a cam 61.

The plow 20 is integral with or mounted upon a rod guided forvertical'reciprocation within the head 6|. The upper end of the rod 10is yieldably held in contact with the cam 61 as by a spring II and thecam is so formed that the rod I0 and its plow 20 are given one or more 4complete reciprocations for each rotation of the shaft 63.

The rolls 30 are rigidly secured to the lower ends of shafts 60 and 0|provided at their upper ends with worm wheels 32 and 93 which mesh withthe threads 66 and 66 respectively. The shafts 30 and 3| are Journaledin bearings so that they rotate freely. The shaft III is carried by aslide 34 so that, should occasion arise, it may be shifted forwardlyfrom the shaft 90. This construction is similar to that set forth in theabove patent.

The hold down applicator 40 is held in position by a clamp or strap atone end of an arm 9I mounted upon a flange 92 on the head 6|. Adhesiveis supplied to the applicator from a tight tank or reservoir 93 suitablysupported in the frame 60 and connected to the applicator by a tube 94.Mounted within the tank is a vertical pipe 96 the upper end of whichterminates at the upper wall of the tank and the lower end of whichprojects below the bottom wall of the tank. Ports 96 in the pipe nearthe bottom of the tank admit adhesive into the pipe and port 91 connectsthe pipe to the tube 94. The lower end of the pipe 96 is closed by aremovable plug 99 the upper surface of which is at the lower edge of theport 91. A plunger 99 normally positioned just above the ports 96 iscarried at the lower end of a rod I00 which extends through a bearingring IOI beyond the top of the pipe. The plunger 99 may be depressed inany-desired manner as for example by a lever I02 pivoted at one end upona bracket I03 and connected at the other end by a link I04 to a treadle(not shown). The rod I00 is connected to the lever I02 by a stud I05which is received in a slot I06. Suitable means such as a spring I01 areprovided to return the plunger to its normal position.

The space in the pipe between the ports 96 and 91 is preferably suchthat it will hold the amount of adhesive required to treat one shoe.Hence only a single complete depression of the plunger will be requiredduring the lasting of each shoe. The preferred adhesive is of the typethat will set quickly when exposed to the air. Various types of suchadhesive are known, most of which are thermoplastic. In order tomaintain the adhesive in condition, the tank 93 is provided with heatingmeans I00, the tube 94 and the applicator are provided with aninsulating jacket of any suitable type, a portion of which is indicatedat J, and a supplementary heater I09 is provided at the toe H. Thetemperature to which the adhesive is raised may be varied according tothe conditions present during the lasting e. g. material employed in theupper or platform under which the lasting takes place. Should it befound that the temperature of the adhesive is too high for theparticular operation, a jet of cool air may be applied through a jet IIO(Fig. 1).

The blades 5| and 52 of the wiping means 50 are reciprocated by therotation of a shaft I20 (Fig. 6) mounted in the frame 60. Fixed upon theshaft I20 are cams or eccentrics I2I and I22 enclosed by straps I23 andI24 upon rods I25 and I26 pivotally attached to the blades SI and 52,the members I2I and I22 being so designed and mounted as to cause theblades 5| and 52 to reciprocate in out of phase relationship. The outerends of the rods I25 and I26 are supported by brackets I21 and I29depending from plates I29 and I30 slidable in guides I3I and I32 fixedto the under face of the flange 92. Rigidly suspended from the head 6|are cam plates ill and Ill. Rolls I35 and I86 on the blades BI and 52are held yieldably in contact with the cams as by springs I31 and I38.Hence, as the blades SI and 52 are advanced, the outer ends thereof arecaused to press the lasting margin down firmly against the platform. Itwill be noted that the forward ends and the bottom forward edges of theblades are rounded to prevent any injury to the lasting margin. Since itis desired that the blades SI and 52 act upon the lasting margin at anangle to the axis of the shoe, it will be understood that the shaft I issimilarly positioned.

The operation of the lasting machine will now be described, it beingunderstood that the shafts i3 and I20 are rotating and actuating thevarious elements as herein above described. The shoe (comprising anupper, a wrapper and a sock lining duly assembled and pulled over a lastand having a platform adhesively secured to the sock lining) ispresented by the operator to the machine with the wrapper depending. Theshoe is held with the platform ll firmly in contact with the boss 34 andthe under face of the toe ll so that the shoe bottom is substantiallyhorizontal. (See Figs. 2 and 3.) A portion of the wrapper is engaged andraised or up -lasted by the plow 20 so that it will enter the bite ofthe rolls whereupon the upper is drawn snugly around the last andagainst the edge wall of the platform and advanced as set forth in theabove mentioned patent. The wiper blades 5| and 52 press the lastingmargin down against the platform, the portion of margin between therolls and wipers being bent over the upper face of the toe ll. Due tothe composite motion of the blades, the lasting margin is both wiped andhammered down against the platform.

The operator, at the proper time, depresses the treadle and starts theflow of adhesive. The pressure exerted by the plunger 99 upon theadhesive in the line will break any film that might be formed in themouth of the outlet passage 43, and the roller 44, being in contact withthe lasting margin, is positively rotated thereby to insure delivery ofadhesive to the lasting margin. As pointed out above a single depressionof the plunger 99 will feed enough adhesive to insure the bonding of thelasting margin of each shoe.

Should additional adhesive be required, the operator can depress thetreadle a second time until the lasting of the shoe is completed.Alternative to the described arrangement, provision may be made forestablishing fluid pressure within the tank 93 and the depression of thetreadie caused merely to operate valve mechanism to control the outflowof adhesive, which flow will continue so long as the treadle isdepressed.

While means are disclosed by which adhesive is applied both to thelasting margin and to the platform, it will be understood that undercertain conditions adhesive need only be applied to one of such partsand that the hold down applicator will be modified accordingly, as byomitting the roller 44 and applying adhesive through the outlet passage43 or by omitting the outlet passage 43 and applying adhesive by theroller 44. Under certain conditions the wrapper may be uplasted by theoperator before the shoe is presented to the machine. When this takesplace the slide 84 may be actuated as set forth in the above patent toseparate the rolls 30 so that the wrapper can be positionedtherebetween, whereupon the slide is returned to its normal position 6and the wrapper gripped between the rolls. The lasting operation is thencompleted as described above.

The essence of this invention resides in the provision and operation oi.the lasting elements 20, 30, Ill and I0 and while one means forsupporting and operating such elements is shown in the drawings anddescribed in detail it will be understood that other means forsupporting and operating such elements may be employed without departingfrom the spirit and scope of the invention.

This invention has been shown in the drawings and described herein asemployed in the manufacture of shoes of the "California" type. It willbe understood however that it is not limited thereto and is applicableto the manufacture of other types of shoes. The claims are accordinglyso drawn. The term "lasting margin" used therein covers not only thewrapper herein described which constitutes an extension of the upper,but also the margin of the upper itself in case no wrapper isprovidedand the term sole includes not only the platform herein disclosed butthe insole, cushion or other intermediate sole.
